These text files contain Mann Kendall statistics for EMEP ozone data for three periods: 
1990-2001
1990-2012
2002-2012

Two metrics are given in the files: 
means of daily mean
means of max daily 8h running values

The metrics are calculated based on five segments of the year
The whole year (one value per year)
Each of four seasons (DJF, MAM, JJA, SON) - also one value per year

All values are given in ppb. 75% data capture each year and for the length of the trend are required.
The files give the significance (0/1), slopes, intercepts and relative trend (in %).

The file names indicate the type of period/metric included in the file 
(e.g. m1_3_m2_6 -> spring time (MAM) etc)
